So You Think You Know Antietam? The Stories Behind America's Bloodiest Day offers descriptions and photographs of 129 monuments and sites on the Antietam/Sharpsburg battlefield. GPS coordinates are given for every site. Much of the photography is in color with several black and white wartime images, including portraits of officers. Included are the Lincoln-McClellan Meeting site, the farms, special topographic features such as the Rock Ledge in the West Woods, the Antietam train station, Lee's headquarters, Sharpsburg's Slave Block, and the National Cemetery. War Department markers, wayside markers, artillery pieces, hospitals, fences, and reenactors are briefly described in the final chapter. The appendices includes the full text of Lee's Special Orders 191, the Federal and Confederate Orders of Battle, and the U.S. Congressional Medal of Honor winners.
